Automotive programmable solenoid controller adds precision in direct fuel injection
The MC33816 programmable solenoid controller embeds intelligence with four integrated μCores, enabling four parallel tasks to run independently of a main system microcontroller. The result is a response time up to a claimed 16-times faster than traditional architectures, for precise fuel delivery that reduces unnecessary fuel use.
Freescale comments that increasingly stringent fuel efficiency standards require highly advanced analogue technologies: the intelligent MC33816 controller also provides embedded encryption and microcode protection to inhibit reverse engineering and help safeguard system IP and software.
